I have migrated this site from Drupal 6 to Drupal 8. I'm not much of a themer so, as you can see, the theme is just Bartik with a slightly custom header. Yes, I know the colors are not quite around the ladder line at the top but it's all I can do for now :)
UPDATE: I've had some problems with Mollom so I've switch to Honeypot with a long time delay which is working quite well.
I've been spending much of my spare time recently learning Drupal 8. It's an amazing project. I'm looking forward to working with it on a real project.
